STATISTICAL
ANALYSIS

Multivalued tables containing symbolic values are converted into one-valued tables called

In turn, one-valued tables may be converted into

The most powerful technique offered by

The report gives the Eigenvalues (inertia of the axes), the projections of each object and attribute onto the first 4 axes and the contribution of each axis to the definition of each point and the contribution of each point to the definition of the axes. Projections in planes [1,2] and [1,3] are proposed by default, but any other plane may be represented. The HAC is also displayed and classes may be colorized to help visualization.
